tion is in the provision of a novel method of applying a lithographed sheet to the display board simultaneously for preventing it from warping or buckling.

Another object of the invention is in the provision of a display mounting in which thelining sheet and printed sheet are applied simultaneously to a board having a cut-out, and thereafter removing the lining sheet by die cutting.

A further object o f tlie invention is in the y method of preparing a mounting board by removing the lining sheet at the back of a cut-out portion by means of a die of the same size or slightly larger than the actual cutout, the lining sheet within the cut-out then being torn from the back of the display board. o

Other objects of the invention will appear hereinafter, the acompanying drawing illustratingmoreor less diagrammatically the method for carrying -out the invention.

Inthe drawing, Fig. l representsa cutting die applied to a display board for cutting it;

Fig. 2 isa face view of a display board with a cut-out design-in it;

Fig. 3 is a diagrammatic view illustrating a cut-out board as it passes about` the paste through paste appliers for both sides of the board and to receive sheets on both sides of the board;

Fig. 4 is a sectional detail view illustrating the. application of a cutting die to one side of a coated displayboardl and about lto cut-out showing the torn edge of the cut-away facing `s eet. f

In general the method of mounting the board is first to die cut the cardboard with `any desired desigmthen to mount the cardboard with paper by applying simultaneously two sheets at the opposite sides of the board over the opening, the paste being applied Aonly to the board, so that it is not applied to the mounting sheets at the cut-out portion, and then to cut out one of the mount-k ing sheets with the saine die which makes the opening in the board, or with a die slightly larger than the opening, so that the paper at one face ofthe board may be removed, leaving only the other face sheet extending over the opening.

Referring now more particularly to the drawing and to the method of carrying out the invention, a board 10 of thick paper or cardboardis first thoroughly pressed,'rdried and rolled to remove all surplus moisture and any desired cut-out design 11 is formed by means of a die 12, the opening or cut-out being entirely through the board.

The board with the cut-out is then passed between upper and lower pasters 13 and 14 having paste applying vrollers 15 and 16 which engage the opposite faces of the board, applying the paste .equally to the faces of the board so that it is equally moistened on both sides. To the paste covered board are then simultaneously applied liningand lithographed sheets 17 and 18 which are represented as being applied by rollers 19 and 20 respectively. Thesesheets areA smoothlypressed against ythe opposite pasted surfaces of the board and the paste is not applied to thel coating sheets so that in the cut-out portions the cover sheets are not pasted.

After the cover sheets are firmly attached, by the paste, either by drying or by allowing them vto set and harden on thel board, the covered board is again applied to a cut-,out

Y die 21having the same or a different design les Vso

`be irregularly torn as illustrated in Figures 5 and 6 and the edge of the board 10 surrounding the eut-out opening 11 may also be partially torn away at the edge 23 of the opening as also shown in Figure 6. Thistearing however is not sufficient to destroy the cut-out opening 1l and when the lining sheet is removed, the other cover sheet 18, usually the outside sheet which bears the printing or lithographing, is unbroken and when there is no strong light behind the board l0 the display looks like any ordinary mounted display sheet. Vhen a strong light or a fiasher is positioned behind the board the cut-out portion of the board will appear to be illuminated, thus forming an attractive display which draws attention to the display and particularly to the illuminated part.

In first drying the cardboard sheet to which the mounting sheets are applied, it is dried beyond or less than its normal humidity so that it will not be too wet when paste is applied to both sides thereof.

By applying the paste and the opposite cover sheets at the same time, the cardboard dries evenly on both sides, thus reducing the tendency to warp or buckle.

The natural shrinkage of the cover sheets and the cardboard when the paste is dry or set, causes the cover sheet which is retained over the cut-out or opening, to be drawn taut and smooth, and when viewed from the front with no stronger light behind it, it presents the appearance of any iiat printed or ornamental display, which may be varied, as for night use, by placing a light behind the cutout.

I claim:

l. The method of display cardboard mounting which comprises drying the cardboard to less than its normal humidity, in simultaneously pasting a face and a lining sheet to opposite sides of the cardboard, thereby preventing the board from warping when theV paste is dry.

2. A method of cardboard mounting which comprises drying the cardboard beyond its normal humidity, applying paste to the opposite sides of thecardboard, and then applying cover `sheets to opposite sides of the pasted cardboard so that the paste when dry will not warp or buckle the cardboard. v

3. The method vof mounting cardboard disl, plays having perforations therein which consists in drying the cardboard beyond its normal humidity, in pasting cover sheets on the opposite faces of the cardboard covering the perforations, the drying of the cover sheets and the expansion of the cardboard drawing the cover sheets tautly and smoothly over the perforations.

4. A method of mounting cardboard displays having perforations therethrough which comprises applying paste to the faces of the cardboard, in applying front and lining sheets to the opposite pasted faces of the cardboard, and in removing the lining sheet at the perforations.

.5. The method of mounting a perforated cardboard display which consists in simultaneously applying paste to the opposite faces of the cardboard, in applying cover sheets to the opposite pasted faces and in removing the cover sheet over the opening at one side of the cardboard.

cardboard display sheet which consists in simultaneously applying paste to the opposite faces of the cardboard, in simultaneously applying cover sheets to the opposite pasted faces of the cardboard, and in removing the cover sheet from over the perforation at one side of the board after the paste sets.

7 The method of mounting cardboard dis- `play sheets which consists in perforating the cardboard, in applying paste to the opposite sides thereof, in attaching cover sheets to the pasted sides and in removing the cover sheet from the opening at one side of the cardboard.

8. The method of mounting cardboard display sheets which consists in die-cutting an opening through the cardboard, in pasting cover sheets on opposite faces of the cardboard over the opening and in die-cutting a cover sheet to remove uit from one side of the board.

9. The method of mounting cardboard display sheets which consists in die-cutting an opening of desired shape in the board, in pasting cover sheets on opposite faces of the board over the opening and in removing the cover sheet on one side of the'board by means of the same die or one slightly larger and of the same shape as the opening.

l0. The method of mounting a perforated cardboard display which consists in pasting cover sheets on opposite sides of the board and over the perforation and in then die-cutting the cover sheet at one side of the opening into the edge of the cardboard so that this cover sheet can be removed from the opening.

l1. The method of mounting a cardboard display sheet which consists in thoroughly drying the cardboard, in die-cutting an open ing of the desired shape therein, in simultaneously applying paste to the opposite faces of the perforated cardboard, in simultaneously applying cover sheets to the paste covered sides of the board, in drying the cover sheets 6.
